The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt -covered
road and the brakes are not used. Likewise,
you clean
off accumulated salt coating from
brake discs and pads with a few ca utious ap
plications of the brake<=>,& .
Co rrosion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not dr iven regularly or
only for short trips with little use of the
brakes.
If the brakes are not used frequently, or if cor rosion has formed on the discs, it is advisable
to clean
off the pads and discs by brak ing
firmly a few times from a moderately high
speed<=> ,&.
Fa ult s in th e bra ke s yste m
If you should notice a sudden increase in
brake pedal travel, then one of the two brake
circu its may have failed. Drive immed iately to
the nearest qualified workshop to have the
damage repa ired. Drive at reduced speed on
the way there and anticipate longer stopping
d istances and higher peda l pressure¢ _&.
Low brake fluid level
Malfunctions can occur in the brake system if
the brake flu id level is too low . The brake fluid
l eve l is monito red electronically .
Brake po wer ass ist un it
The brake power assist un it increases the
pressure that you generate with the brake

Brake lining wear may be checked by visual in

through the openings in the wheel. If neces

_& WARNING
-You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Other road use rs must not be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear o r lower dr iving range. Do not ride
the brakes or hold the pedal down too
long o r too often. Th is could cause the
brakes to get hot and diminish braking
efficiency .
- Do not " ride the brakes" by resting you r
foot on the pedal when you do not intend to brake. This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain cl imatic and operat ing
conditions such as passing through wa
ter, dr iv ing in heavy rain o r after washing
the vehicle, the effectiveness of the brakes can be reduced. In winte r, ice can
accumu late on the bra ke pads, lin ings,
discs and drum s. Carefully app ly bra ke s
for a test. Brakes w ill dry and ice coa t
ings w ill be cleaned
off after a few care
fu l brake applications.
- Driving for an extended period of time on
salt -cove red roads without using your
brakes can a lso affect braking efficiency .
Clean
off accum ulated salt coating from
brake discs and pads with a few cautious
brake applications.
- I f you damage the front spoiler, or if you
install a different spoiler, be sure the air
f low to the front brakes is not obstruct
ed. Otherw ise the brake system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one b rake circuit will impai r
the braking capab ility result ing in an in
creased stopping distance. Avoid driving
the vehicle a nd have it towed to the near
est A udi dealer or qualified workshop .
- Never let the veh icle roll to a s top with
the engine shut
off. .,.

WARNINGS. The engine compartment of any
vehicle is a hazardous area!
c::> &.
A WARNING
To help avoid injury, before you check any
thing under the engine compartment lid:
- Switch off the engine.
- Remove the ignition key.
- Apply the parking brake.
- Move selector lever of S tronic to "N"
(Neutral); put manual transmission in
Neutral.
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the engine compartment lid if you
see or hear steam or coolant escaping
from the engine compartment. Wait un
til no steam or coolant can be seen or heard before carefully opening the en
gine compartment lid .
- Keep children away from the engine com
partment .
-Never spill fluids on hot engine compo
nents. They can cause a fire.
- Never open the coolant reservoir cap when the engine is still warm. The coolant system is pressurized and hot cool
ant could spray out.
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri
cal system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames. Fluids in the engine com
partment could start a fire.
- Keep an approved fire extinguisher im
mediately available.
- To avoid electrical shock and personal in
jury while the engine is running or being
started, never touch:
Checking and filling 173
- Ignition cables
- Other components of the high voltage electronic ignition system.
- If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever of S tronic to "N"
(Neutral); put manual transmission in
Neutral.
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get
ting caught in the radiator fan, V-belts
or other moving parts, or from contact ing hot parts. Tie back hair before
starting, and wear no clothing that will hang or droop into the engine.
- Minimize exposure to emission and chemical hazards

A WARNING
California Proposition 65 Warning:
- Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth de
fects and reproductive harm. In addition, certain fluids contained in vehicles and
certain products of component wear con
tain or emit chemicals known to the
State of California to cause cancer and birth defects or other reproductive harm.
- Battery posts, terminals and related ac
cessories contain lead and lead com
pounds, chemicals known to the State of
California to cause cancer and reproduc
tive harms. Wash hands after handling.
@ Note
When adding fluids, always make sure that
they are poured into the proper container
or filler opening, otherwise serious dam
age to vehicle systems will occur.
@ For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly. If
you see spots from oil or other vehicle

for use throughout the life of your A udi.
Whether yo u use syn thetic or petroleum

are synt het ic eng ine oi ls . Th is does not mean,
however, that every synthetic engine oil will
